Numerical Study on Acoustic Field Generated by Dipole Sources in Noncircular Pipe
Acoustical well logging is an important technology for petroleum industry. Calibration and testing of tools in real wells is not feasible because the cost is high and the condition is not controllable. During manufacturing and maintaining, the logging tools are usually tested in a fluid ... En savoir plus
Modeling two-phase flow in strongly heterogeneous porous media
Modeling Two-phase flow through strongly heterogeneous porous media is of importance in many disciplines including petroleum industry, hydrology etc. There are, however, still some challenges in numerical simulation of such flow problems especially the flows in fractured porous media and ...

Designing Silver Nanowires Invisible Cloak Based on Effective Medium Approach
In this section, we design an invisible cloak using the composite medium of silver nanowires with elliptical cross-sections embedded in a polymethyl methacrylate host. Under the guidance of an analytical effective medium approach, we use the parameter retrieval method to design a well ... En savoir plus
Strong Magnetic Field and Its Application
High magnetic field research has yielded fruitful results. Since 1913, associated with the magnetic field there are 19 Nobel Prizes, including a prize for medicine, five chemistry prizes, and 13 physics prizes. In recent years, the international community under the conditions of strong ... En savoir plus
Magnetoacoustic Tomography and COMSOL Multiphysics
Magnetoacoustic tomography with magnetic induction (MAT-MI) is a recently introduced method for imaging electrical impedance properties, which integrates classic electrical impedance tomography and ultrasonic technique. It could provide an explicitly reconstructed electrical impedance ... En savoir plus
